PIPE-CLAMP.

Specification of Letters Patent.

Application fil edlanuary 7, 1913. Serial No. 740,672.

Patented July 28, 1914.

To all. whom it may concern Be'it known that I, CLAIR MCCARD, a citizen ofthe United States, residing at Divide, in the county of Laramie, State of Wyoming, have invented certain new and useful Improvements in Pipe-Clamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to pipe clamps.

The object of the invention resides in the provision of a device of the character named which may be adjusted to fit any size of pipe and which may be conveniently clamped upon the latter.

A further object of the invention resides in the provision of adevice of the type named which includes improved means ator drawing together the grip-ping memhersoi the clamp so as to obtain varying degrees of pressure upon the pipe and also to provide for locking such means so as to prevent accidental separation of the members of the clamp and consequent dropping of the pipe.

\Vith the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claims.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the sev eral views, and in which Figure 1 is a plan view of a clamp constructed in accordance with the invention.

Referring to the drawings, the clamp is shown as comprising opposed cooperating members 10 and 11, the member 11 being slightly longer than the member 10 but simi lar in general shape. The members 10 and 11 have their terminals disposed in registration at one end and are provided respec- Fig.

. tively at that point with registering passages 14: provided with a series of openings 15.

The ends of the members 10 and 11 remote from the arm 14 are provided with register ing passages 16 and'17 respectively. Pivoted in the passage 16 and extending through the passage 17' is an arm 18 pro vided with a pluralityof openings 19. The passages 1213 and 16 -17 are'sutficiently large to permit a certain amount of pivotal movement of the arms 14 and 18 respectively.

Mounted on the end of the member. 11 remote from the passage 13 and outwardly of the adjacent end of the member 10 is a pair otspaced cars 20 and 21 between which is pivotally mounted an operating lever 22. The end of the operating lever 22 disposed inwardly of the ears 20 and 21 is provided with a passage 23 through which the arm 18" extends. The adjacent bases of the members 10 and 11 are provided with mating recesses 24 and 25 respectively and smaller mating recesses 26 and 27 respectively which form sockets for the reception of pipe during the clamping operation.

In the use of the device the members 10 and 11 are positioned on opposite sides of the pipe to be clamped and a pin 28 inserted in a desired recess 15 of the arm 14, said pin being disposed on the outer side of the member 11. The members 10 and 11 are then brought together so as to dispose the pipe in either the mating recesses 24 and 25 or the mating recesses 26 and 27 dependent on the diameter of the pipe. A pin 29 is then inserted in one of the openings 19 of the arm 18 outwardly of the operating lever 22. The outer end of the operating lever 22 is then moved inwardly toward the member 11 and as the inner end of said lever will engage the pin 29 it will be apparent that the member 10 will be drawn toward the member 11 and the clamping of the pipe eifected. If it is desired to maintain the pipe clamped by the device it is only necessary to insert a pin 30 in the opening 19 of the arm 18 which is disposed next to the outer side of the device for clamping and holding pipes during well construction and preventing such pipes from falling into the well.

What I claim is a 1. A pipe clamp comprising a pair of cooperating members hingedly connected at one end and provided with registering passages adjacent their other end, an arm pivoted in the passage of one of said members and extending through the passage of the other, said arm being provided with a plurality of openings, an operating lever pivotally mounted on the last named member and having its inner end provided with a passage through which said arm extends, and a pin interchangeably insertible in the openings in said arm outwardly of the inner end of said lever whereby the movement of the outer end of said lever toward the adjacent member will bring the inner end thereof into engagement with said pin and draw said members toward each other.

2. A pipe clamp comprising a pair of cooperating members having registering passages therein adjacent one end, an arm pivoted in the passage of one of said members and extending through the passage of the other member, said arm being provided with a plurality of openings, a pin inserted in one of the openings between the free end of the arm and the adjacent member whereby the members are hingedly connected, said members being further provided with registering passages adjacent their outer ends, an arm pivoted inthe last named passage of one member and extending through the last named passage of the other member correspondingly to the first named arm, said last named arm being provided with a plurality of openings, an operating lever pivotally mounted on the member through which said last named arm extends and having its inner end provided with a passage through which said last named arm also extends, and a pin interchangeably insertible in the openings of said last named arm outwardly of the inner end of said lever whereby the movement of the outer end of said lever toward the adjacent member will bring the inner end thereof into engagement with said pin and draw said members toward each other.

In testimony whereof, I afiix my signature, in presence of two witnesses.
